Abstract: On the phthalocyanines of 17 metals, investigations were carried out concerning the influence of nuclear recoil and radiation effects on the yields of separable radioactive meta! atoms and their retentions, respectively. A broad comparison on many different elements revealed for the (n, $\gamma$)-, (n, 2n)- and (n, p)-nuclear reactions as well as for the $\beta$-decay, isomeric transition and K-capture process characteristic relations of the available recoil energy, radiation chemical influences, charge and excitation of the atoms and molecules on chemical band rupture and annealing. From the results it may be realized what an important part repelling forces due to nuclear processes must play in liberating meta! atoms out of the phthalocyanine molecules. It was further established that foreign species present in the samples, particularely oxygen, strongly influence recombination reactions. Heating or prolonged evacuating of the compounds prior to neutron activation causes an increase in retention. Quantum radiation induces a relatively strong radiation decomposition of the phthalocyanine compounds, which is however superimposed by annealing.
